No. 287,069 Claims priority, application Italy, June 16, 1962, 12,182/ 62 3 Claims. (Cl. 17325) The present invention relates to a depth drilling machine.

An object of the invention is to provide a construction wherein no winch-supporting truss for the drawing winch of the tubular rods coupled with the drilling bit is required.

A further object of the invention is to provide means for drawing and winding a cable connected to the tubular rods of the bit which will slide upon rollers.

A still further object of the invention is to provide a winding roll which will operate synchronously with the rotary unit which drives the bit.

A still further object of the invention is to provide a construction which can be mounted upon a truck capable of being driven wherever desired.

A still further object of the invention is to provide a drilling machine which may be quickly transported from one location to another and which can be immediately placed in operation thereby saving time and effort.

For better understanding of the invention reference is made to the attached illustrative drawings, wherein:

FIGURE 1 is an exploded side view with parts in section of the main parts of the device;

FIGURE 1A is a top plan view of the member II in FIG. 1;

FIGURE 2 shows a side view of the assembled device with certain parts broken away in vertical section;

FIGURE 3 shows a side view of the device assembled on a truck;

FIGURE 4 is a vertical section taken along the line 44 of FIG. 4A;

FIGURE 4A is a horizontal section taken along the line 4A4A of FIGURE 1;

FIGURES 5 and 5A shows two different embodiments for coupling the tubular rods with one another.

FIGURE 1 shows the various component members before being assembled. The rotary main cylindrical body A is mounted on a roller bearing 1 placed on a suitable housing therefor provided on the assembling surface B. A similar roller bearing 3 (I) is located above a member D referred to below.

Moreover, the cylindrical body A is reduced in size at at 2 at the top portion thereof. A window 4 is provided for the passage of the draw cable of the tubular rods connected to the drilling bit. A helical spur gear 5 is integral with the rotary cylindrical body A and meshing with the similar pinion 6 supported by a suitable support 7 therefor. The support 7 supports a further pinion 8 similar to the preceding one 6 and designed for meshing with the gear 9, similar to the gear 5, but provided on the takeup roll C, with room 10 for winding the already mentioned draw cable. The roll C is the third member (111).

The second member D (II), namely the one which in the order (I-II-III) precedes the take-up roll C, besides being designed to retain the take-up roll C in position, provides for guiding with its pulleys 11 and 12 the cable issuing from the eye 4 of the main body A.

It can be observed that the window 4 recurs in said member D and that in the same is arranged the first pulley 11 designed for guiding the issuing cable and thence the second pulley 12 which, in a slanting position,

"Ice

guides the cable on the take-up roll C-10. Secondary small-size pulleys X suitably positioned close to the main pulleys 11 and 12, prevent the cable from escaping from the main pulleys.

It is evident that for the setting up of the assembly, the members IIIIII are to be inserted on the cylindrical body A according to the above mentioned order. The member D is shown in plan in FIG. 1A so that, by screwing down the screws 13 of the jaws 14 and 15, the latter press against the cylindrical body A to fasten on. the body A, the member D.

FIGURE 2 shows an elevational view of the drilling apparatus, somewhat enlarged. In the figure, there is shown from top to bottom: the first roller bearing 3 (I); the band D carrying the pulleys 11 and 12 (II); the takeup roll C10 (III) and the main cylindrical body A. It is understood that the take-up roll C rotates independently on the cylindrical body A since it is provided with a gear 9 of its own and a pinion 8 of its own. It is evident that the rotary cylindrical body A acts also as an axle for the roll C. The assembly is partly cut away to show, at the interior, the engageable length-tubular rod 16, with the pulley 17.

The two pinions 6 and 8 connected with the reverse run device M through the two connector axles 18/ a, can rotate in the same direction simultaneously and alternately being at all times in mesh with the gears 5 and 9. In fact, upon drilling, the cylindrical body A and the take-up roll C rotate in the same direction and at a slightly different speed for the roll C, by losing some revolutions in comparison with the rotary body A, this can permit the gradual unwinding of the cable and the gradual loosening of the same for the desired rundown of the drilling bit connected to the tubular rods. Upon the rewinding of the cable 18 for the draw of the drilling bit, they rotate on the contrary in an alternate way: namely, while the take-up roll C provides, as already stated, for drawing the cable 18, the main body A remains stationary or rotates, if desired, in an opposite direction for a faster lift of the drilling bit. Such an alternative is controlled by means of suitable levers operated from the drive place. s

Should the driver accidentally incur a control mistake and the take-up roll should rotate for a while in a reverse direction as far as to cause a loosening of the cable 18, a bafiie plate E placed inside the cover E/a prevents the cable from ruinously entangling in the underlying members.

For the same purpose it is also possible to extend the diameter of the gear 9 as far as the wall of the cover E/a.

The heavy assembly is covered by a metal cover E/a and placed on a suitable four-wheeled truck therefor, driven by means of a conventional steering gear.

FIGURE 3 shows the four-wheeled truck having a frame F in a preferable shape and suitable for the laying of the apparatus. The cover E/ a thoroughly covers the assembly and under the truck is clearly visible the drilling bit G.

FIGURE 4 shows the tubular rods 16 provided with two guide-splines 19 and forced to slide on four giude rollers 20 arranged inside the main cylinder A.

FIGURES 5 and 5a show various coupling systems between the connecting parts 16 and 16' with guide-splines 19 and 19'. In the first case the offsetting can be noticed of the two ends H and K, whereas in the second case it can be observed that the two ends are mating and that only the offsetting of the two splines 21 provides for the locking of one end onto another. The pin 22 is at all times designed to enter the hole 23' therefor. Two screws 24 provide for securing the pin 22.

Various embodiments are possible without departing from the spirit and the scope of the invention.
